Denny - I've heard similar things before, but I also read an article about a study on this that seemed to say it needed significant exposure for detectable levels of "skunking."
I'll look for that article. I can't recall where I read it, but it was interesting. IIRC they did three tiers of exposure and were pretty methodical.
EDIT: There's too darn many post on-line for me to find that article ever again. I guess if it tastes skunked to you, that's enough for me.
Yeah, it was very definitely skunked. A very hoppy IPA and very bright direct sunlight.
